Same thing happened to me. I was waiting at the dealership, getting the 1200 mile service, and my SA came out and told me they were embarrassed as they didn't have the oil filter in stock. Had to leave the car overnight, was ready the next day. Gave me a X5 diesel to drive home. Also gave me a BMW hat and coffee mug, and 4 quarts of oil

Well you did much better than me!! lol. I just received a very nice sorry! How on earth could a BMW dealership not have the correct oil filter in stock? And I'd still be surprised if it's a different filter that that used by the 550.
